dc.descriptionA sequence of generations of the polyamideamine dendron, PAMAM-talc-Gn (n = 1-7), was constructed on the surfaces of ethylenediaminepropyl-functionalized magnesium phyllosilicate lamellas by using a modified microwave-assisted synthesis. The successful functionalization of the inorganic layers by the organic dendrimer was confirmed by FTIR and C-13 NMR spectroscopies, elemental analyses, and thermogravimetric analysis (TGA). The solid materials presented an increase in their interlamellar space and disorganization of lamella packing with the growth of the dendrons. Thermal-programmed desorption analysis showed that the lower dendron generation, PAMAM-talc-G1, adsorbed 1.30 mmol of CO2/g of sorbent at 30 degrees C. PAMAM-talc-G5 adsorbed the double of PAMAM-talc-G3, probably due to the higher amount of the primary amine group; however, PAMAM-talc-G5 adsorbed more CO2 than PAMAM-talc-G7 probably because in the delaminated seventh generation intradendron N-H interactions were more prevalent than in the fifth generation and blocked CO2 interaction sites.
